This method works on once-living organisms, including objects made of wood or other plant material.

Carbon is a long-studied element, but that doesn't mean there isn't more to discover.

In fact, the same element that our prehistoric ancestors burned as charcoal may be the key to next-generation tech materials.

In 1985, Rick Smalley and Robert Curl of Rice University in Texas and their colleagues discovered a new form of carbon.

Under very hot temperatures — greater than 100,000,000 Kelvin (179,999,540.6 F) — the helium nuclei begin to fuse, first as pairs into unstable 4-proton beryllium nuclei, and eventually, as enough beryllium nuclei blink into existence, into a beryllium plus a helium.

The end result: Atoms with six protons and six neutrons — carbon.

Since then, other new, pure carbon molecules — called fullerenes — have been discovered, including elliptical-shaped "buckyeggs" and carbon nanotubes with amazing conductive properties.Carbon-14 has a half-life of 5,730 years, meaning that after that time, half of the carbon-14 in a sample decays away, according to the University of Arizona.Because organisms stop taking in carbon-14 after death, scientists can use carbon-14's half-life as a sort of clock to measure how long it has been since the organism died.Sign up for INFObytes and receive an MP3 (audio presentation) called Genesis, The Gospel and the Creation/Evolution Issue by Dr Emil Silvestru—free for you to download! As the sixth-most abundant element in the universe, carbon forms in the belly of stars in a reaction called the triple-alpha process, according to the Swinburne Center for Astrophysics and Supercomputing.

In older stars that have burned most of their hydrogen, leftover helium accumulates.
